If the Superbowl halftime show wasn't enough for you, let me present you with an alternative. Compressorhead, the world heaviest metal band. Have ever wondered what a drummer could play if they had 4 arms? What about a guitarist with 78 fingers? If this cover wasn't quite to your liking, you can always request one on their website CompressorHead. Personally I'm still waiting on a Rush cover of Tom Sawyer, but it won't be long.
